IMPROVEMENT IN COAL-ELEVATORS.

The Schedule referred to in these Ietters Patent-and making part of the same.

Toall whom, 'it 'may concern Be it known that 1, LEWIS S. GHIcHns'rnn, of the city and State of New York, haveinvented and made a certain new and useful Improvement in Elevators for Goal, Sac.; and I do hereby declare the following to be a full, clear, and exact description ofthe said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is au elevation of my hoisting-apparatus, showing also the tioat for the hoister, the canal-boat or barge for the coal, and the vessel into which it is to be delivered in section, and

Figure 2 is an elevation of the hoisting-apparatus at right angles to g. 1.

Similar marks of reference denote the same parts.

Heretofore diiiicult y has been experienced in coaling or loading vessels from barges or canal-boats. It has lusually been done contiguous to a dock, upon which a horse might walk to hoist the bucket.

A large number of vessels receive their coal when lying at anchor in the harbor or river. This involves the necessity of rigging up, temporarily, Va hoisting-apparatus, and using a large number of men or a horse on the vessel to' be loaded.

A chain ofr buckets has been employed, as in the patent of June 27, 1865, reissued November 24, 1868, No. 3,206, to Nichols, Chichester, and Mills. This, however, was not as well adapted to elevating vlarge lumps of coal as a single bucket, to be raised and lowered.l

The nature of my present invention consists in combining withy a float, a hoisting-apparatus, operating upon a bucket, to elevate the same, and draw up the coal or other material, and tip 'it into .the chute that delivers the said coal into the vessel that is to receive it.l

By this apparatus, the transfer of coal and similar material from canal-boats or barges to ships orvessels, can be eiected with very'great rapidity, as the .elevator can be floated' from place to place, and is always ready for use, and the canal-boats or barges can be moved-out in succession, and others brought into place, so as to avoid the delay now usual in such cases.

In the drawing- The section a illustrates the vessel to receive the coal or other material, and

1) the canal-boat or barge, from which said material is to be taken and transferredto a, and Y c is -a float, of suitable size, that should be fitted with a propeller, to move it from place toplace, and an engine, forv actuating the same and the hoistingdrums d d.

eis a frame-Work, rising from the Ifloat c, and. carrying, at a proper height or adjustably, the chute or spout f, to convey the coal into the vessel that is to receive it, and i g g are the swinging buckets, suspended by the bails h and ropes or chains i, that pass over blocks or pulleys k to thedrums d.

These ropes t' should pass upon the drums d in ops' posite directions, so that one bucket will be lowered as the other one is drawn up; `and in order to tip the buckets in the act of hoisting, and cause the' contents to run into the chute f, I make use of the hooks ld, on the sides of the chute f, taking the edge of the bucket.

By this apparatus, the transfer of coal and other material by a reciprocating bucket or buckets is very greatly facilitated, because the hoisting-mechanism can be moved from place to place, and is independent of the vessel that receives the material and of the boat or barge that brings the same, and therefore the latter can be'moved away to admit anotherboat, without disturbing the relative positions of he hoistingmechanism, its float, and thevessel receiving the coal.

What I claim, and desire to. secure by Letters Patent, is-

' Au apparatus vfor transferiiug coal, or similar material, from one'vessel to another, the same consisting in the frame e, supported by the float c, and carrying the chute j, in combination with the swinging bucketsg, suspended by the bail h, and operated Vby the rope or chain t', and drum d, substantially asset forth.

ture, this 25th day of January, 1869.
